Mariner 2.4L Compression

[GreginVT]

I have a 1988 Mariner 2.4L Offshore (240 hp), and I was wondering what the compression should be. I checked the compression (with the motor cold) when I bought the motor 3 seasons ago, and it varied from 120 to 125 lbs overall. How much compression should this motor have? It seems to run pretty strong, but it's no spring chicken. Thanks!!

125 # seems ok as memory serves me. Most important is the fact that they are even.<br /><br />...have fun...corm
